Hi Everyone,
I have been coming here for a while and reading, and its about time I joined. I just got a XR3 as a resto project, and I need to ask a question that I have little knowledge of. A repair panel (About 3/4 Square meter total) had been fabricated and welded in place on the passenger’s side floor on this XR3 that I have just got as a restoration project. The repair has never been painted or had any under body seal, why? I don’t know why, I just know it needs doing. For the rustier part it is going to have a wire brush and Kurust applied, on the “Not so bad, surface rust” it will be cleaned up and Zinc 182 applied. But what I don’t know is…. Can you apply Hammerite under body seal over Kurust and Zinc 182 directly?

Hi. Personally if I were to do protect that surface and without access to 2k paints etc I would

Wire wheel the surface rust with a wire wheel in a drill or on a grinder
Kurust the whole panel
Prime the panel with red oxide primer
Apply seam sealer such as tiger seal or brushable seam sealer to the welds
Apply a further coat or red lead
Paint the patch with coach enamel in a colour of your choice (can get it from car paint stores)
Then underseal it

Or you could alternatively use stone chip and paint over the stonechip dependant on how far you want to go with it.

Oh and the reason I wouldn't use zinc 182 is because they have a weaker bond when applied onto other products. I would kurust the whole panel to remove any traces of the surface rust and passivate the panel.
